PROPELLING MECHANISM FOR VEHICLES.

Specification of Letters Patent.

Patented J an. '7, 1919.

Application filed August 2, 1918. Serial No. 247,959.

To all whom it may concern:

Be it known that I, CHARLES M. TATOSIAN, a subject of the King of Armenia, residing at Newark, in the county ofEsseX and State of New Jersey, have invented certain new and useful Improvements in Propelling Mechanism for Vehicles; and I .do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beingv had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in propelling mechanisms of the 'mechanism of the general character hereinaftermorefully set forth, whichis simple in its construction, is efliclent 111 its operat on, and is productive in producing greater power, than by means of the usual forms of propelling mechanism now ordinarily 1n use.

The invention has for its further obj e-"t to "provide in connection with the construction 1 of propelling mechanism, means adapted-to be actuated by the operator, whereby the mechanism acts to produce a slack of the chain, so that the me"han1sm can also be .used in the manner of the usual coasterbrake.

. Other objects of this invention not at this time more particularly. enumerated will be 45 clearly understood from the following detailed description of the same.

, With the various objects of the present invention in view, the said invention consists, primarily, ,in ,thenovel propelling mechanism for vehicles, such as velocipedes, bicycles. and the like, hereinafter more fully set forth; and, the present invention consists, furthermore, in the several arrangements and combinations of the several de vices and parts, as well as in the details of the construction of the said parts, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claim which are appended to and which form an essential vpart of the said specification.

The present inventlon is clearly 1 Figure 1 is a side elevation of the said propelling mechanism, as applied. to the frame of a bicycle, portions of the said frame beingalso shown in side elevationin said view; and Fig. .2 is a top or plan view of said propelling mechanism, the main hub and frame-portionof the vehicle, in said view being represented in section.

Fig. 3 is a central longitudinal vertical section of the mechanism, said section being taken on line 33 in said Fig. 2, and said view being made on an enlarged scale.

Fig. 4 isa transverse vertical section taken on line 4+4. in said Fig. 3; Fig. 5 is a similar section taken on line 55 in said Fig. 3; and Fig; 6, likewise, isa transverse vertical section, taken on line 6 -6 in said Fig. 3.

. Similar characters of reference are em- Iployed in all-0f the several figures of the drawings, to indicate corresponding parts. .Referring now to the several figures of the drawings, the reference-characters 1, 2 and. 3 indicate fragmentary portions of the usual reaches of a bicycle-frame, the said rearhes being secured, in any usual manner, to the usual tubular-bearing hub l, closed by the respective end-plates 5 and 6 which are respectively formed with the -bearingportions 7 The reference-character 8 indicates a main shaft or spindle of suitable length, thesaid shaft or spindle being centrally perforated, as at 9, and having mounted-in said perforation a laterally extending pinlO, upon the free end-portions of which are rotatably mounted a pair of bevel-gears 11 and 12,

said gears being maintained in position upon the ends of said pinby means of heads llustrated in the accompanying. drawings, in which:-

or enlargements '13 and. a pair of sleeves 14,

as shownin Figs. 3 and 4 of the drawings. In mesh with the said bevel-gears lland 12 are a pair of bevel-gears 15 and,16,.said

last-mentioned gears having their ihubs loosely and rotatably mounted upon said shaft or spindle 8, on opposite sides ofthe said pin 10. Operatively secured upon the hub of the bevel-gear '15, byimeans of a screw 17, or other suitable fastening means, is an annular sleeve-like member or element 18, which extends from the inner side or face of a hub 19, said hub being also mounted upon a portion of said shaft or spindle 8, and having extending therefrom at the proper'angle a crank-arm or pedal carrying'upon its free end a foot-treadle, as 21. In a similar manner, there is secured upon the hub 16, by means of a screw 22, the annular sleeve-like member or element 23, which extends from theinner side or face of a hub 24, said hub being also mounted upon a portion of said shaft or spindle 8, and having extending therefrom at a proper angle a crank-armor pedal carrying upon its free end a foot-treadle, as 26. As shown more particularly in Fig. 2 of the drawings, the hub 19 is also provided upon its inner side or face and concentric with said sleeveelike member or element 18 with an annular arrangement of ratchet teeth 27,

and the hub 24 is also provided upon its inner side or face and concentric with the sleeve-like member or element 23 with an annular arrangement of ratchet-teeth 28, the direction of the teeth 27 being opposed to the direction of the teeth 28. The positions of the aboveanentioned pedal-carrying hubs 19 and 24 are mounted against movement upon theshaft or spindle 8 longitudinally with relation to said shaft or spindle, by an arrangement of washers 29 .and 30 and nuts 31 and 32 screwed upon the respective screwthreaded end-portions 33 of the said shaft or spindle, and by means of the previously mentioned bevel-gears, as will be .clearly understood from an inspection of said Fig. 3 of the drawings.

As shown, an arrangement of antifriction rollers 34 and 35 "is also disposedbetween said shaft or spindle 8, and the inner surface-portions of the respective sleeve-like elements 18 and 23, other anti-friction rollers 36 and 37 being disposed about the outer surface-portions of the respective sleeve-like elements 18 and 23.

slidably disposed upon the said rollers 36, so as to move in the direction of the arrow as, see Fig. .3, is a sleeve-like member or element, as 38, said sleeve being formed at its one end With an annular off-set, .as 39, against which is fitted and secured by means of screws 40, or other suitable fastening means, a sprocket-wheel 41, for conveying 'motion to the usual sprocket or link-chain 42 Extending from the outer face of the sa1d off-set member 39 18 an annular arrange- .ment of ratchet-teeth 43 normally in engagement with the ratchet-teeth 27 of the pedal carrying hub 19.

Upon its oppositeend-portion, the said sleeve-like member or element 38 is formed Wlt-ll longltudinally extending segmental fig r a and paces 4 a terne e d posed as represented in Fig. 4 of the draw ings, and for the purposes to be presently more fully set forth.

Similarly, slidably disposed upon the rollers 37, so as to move in'the direction of.

the arrow 3 in said Fig. 3, is another sleeve- 49, which extend into'ancl are slidably dis 7 posed in the above-mentioned spaee 45 between the fingers 44, suitable spaces 50,.see Fig. 2 of the drawings, being also provided between the fingers 49 into which extend and are slidably disposed the previously mentioned fingers 44, so that the two members or elements 38 and 47, with their alternately disposed and slidably engaged fingers, will provide a clutch-device for the purposes hereinafter more fully set forth.

Suitably mounted upon the said fingers 49 and surrounding the same, is a stop-ring 51 formed with projecting portions, as 52 which extend into and register with the spaces 5.0 between said fingers 49, as shown in Fig. 5 of the drawings; and, mounted upon the fingers 44 of the member or element 38 is another stop-ring, as 53, also provided with projecting portions, similar to the projecting portions, 52, but not here shown, and

-which extend into and register'wit-h the ment 47 andits fingers 49, between the longitudinal-hub 4, and the endwall 5 and stop-ring .51, other anti-friction rollers 55 being arranged about portions of the sleevelike member or element 38 and its fingers 44, between the bearing-hub 4, and the end-wall 6 and stop-ring 53.

The operation of the mechanism hereinabove described will be selfevident from the foregoing description'of the same, and from an inspection of the several figures .of the drawings, and it suffices merely:to say, that when the operator presses the pedal 25 in a downward direction, in the direction of the automatically move in an opposite and up ward direction, in the direction of the arrow a; and, vice versa, when the pedal 20 is moved downwardlflthe pedal .25 mo es Y arrows, in Fig. 1, the other pedal 20 will automatically in an upward direction, owing to the alternating active engagement of the one set of ratchet-teeth and non-active sliding engagement of the other set of ratchetteeth. Thus, the alternating reciprocatory movements of the respective pedals, and the respective movements of the co-acting parts of the mechanism will produce a continuous rotary movement of the sprocket-wheel ll at all times in one, and the same direction, the shaft or spindle 8 at all times maintaining a fixed non-rotative relation.

In order to brake the vehicle, by what is termed back-pedaling I have secured upon the screw-threaded portions 33 of the shaft or spindle 8, by means of washers 56 and lock-nuts 57, a pair of rods 58, which are connected by means of a cross-bar rod 59, locked to said rods 58 by means of lock-nuts 60 and 61, and provided with foot-actuated means, as 62. The mechanical assemblage of theseveral devices and parts, in such case, is such, that a downward pressure upon either or both of said actuating means 62 produces a slight movement of the shaft or spindle 8 in a reverse direction, against the momentum 1n the forward directlon, thereby, by means of the chain, causin a drag upon the tire of the rear wheel 0 the vehicle, to suddenly stop or brake the vehicle.

To limit and arrest the downward movements of the respective pedals at the proper times, and to provide for the proper working of the mechanism, the said rods 58 are provided with downwardly extending members, as 63, from which extend laterally suitable pins or studs 64, preferably provided with cushioning devices 65 of rubber, or the like, and with which the said pedals are respectively brought at the ends of their downward strokes into arrested engagement, as will be clearly evident from an inspection of Figs. 1 and 3 of the drawings.

From the foregoing description, it will be clearly evident that I have produced a simply constructed and eificiently operating propelling mechanism, and one, while it is operated with but slight exertion on the part of the operator, produces an increased power in operating the vehicle.

I am fully aware, that some changes may be made in the general arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the said specification and the claims appended thereto. Hence, I do not limit my present invention as set forth in the said specification, nor do I confine myself to the exact details of the con structiOn of the said parts, as illustrated in the accompanying drawings.
